TWO MAGNIFICATIONS
Choose the 2-10x40 for maximum reach or the 3-9x40 AO for balanced versatility. Both deliver uncompromising accuracy.
ADJUSTABLE OBJECTIVE BELL
Fine-tune your focus with an adjustable objective bell that corrects parallax for distances as short as 10 meters. Perfect for precision shooting across short and mid-range distances.
ILLUMINATED RETICLE
Red illumination enhances visibility in low-light environments, giving you a clear aiming point when the light starts to fade.
1/4 MOA PER CLICK
Tactile and audible turret clicks provide precise 1/4 MOA adjustments, allowing for quick and consistent zeroing every time you’re at the range.
FULLY-MULTICOATED LENS
Fully multi-coated lenses ensure maximum light transmission and color fidelity for superior clarity, even in low-light conditions.
LIFETIME WARRANTY
Every Marauder is backed by Monstrum’s lifetime guarantee so your optic is protected for life.
